Abstract

Surface area of lands transformed by coal mining in the basin are analyzed. In 1975 there were 3,110.9 ha of waste lands. Of this, spoil banks dumped on the surface covered 1,019.5 ha, spoil banks located in the cuts of surface mines (e.g. where sand is removed for stowing) or in other subsided places covered 1,064.5 ha, and water reservoirs covered 665.6 ha. Composition of spoil banks produced by black coal mines is analyzed from the point of view of land reclamation. A scheme of reclamation of spoil banks used in the Upper Silesian black coal basin is given. Reclamation of 5 large spoil banks is described. The land reclamation procedure consists in: leveling the spoil bank slopes so that their inclination is 1:10 instead of 1:4. When afforestation is used relatively steep slopes (1:4) are not leveled, centers of endogenic fires are extinguished by packing using rollers, the top layer of a spoil bank is mixed with calcium carbonate (3 to 10 kg/ha), then the top layer of waste fertilized by calcium carbonate is covered with soil (in some cases with fertile soil), soil cover ranges from 15 to 30 cm, the top soil cover is fertilized (dose ranges
from 300 to 500 kg/ha). Later lupine is planted and ploughed as additional fertilizer. At a later stage trees and bushes are planted. (10 refs.) (In Polish)More>>
